I am 62 and a 7 time world powerlifting champion. At my age I need all the help I can get and this product is a WINNER! Prior to using this product I would be sucking wind and have a very long recovery time between sets especially squats. I noticed the difference the first time I used the patch. I was still sucking wind but for less than before and recovery was much faster between sets. This allowed mr nto work out faster and with heavier wts. The difference before and after use is like night and day. No matter what exercise you do this path WILL WORK!! Give it a try and I promise YOU WILL NOT BE DISAPPOINTED!!
